Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a method and system used to ensure that a printer which is capable of printing security patterns loses its ability to print these patterns if the printer is disconnected from an approved system and, more particularly, to a method and system including a printer containing an encrypted key and password loaded into its memory, where the stored password must match a password present in a data stream sent from the host software application in order to print a requested print job.

2. Description of the Related Art

Security patterns are used across a diverse marketplace to deter fraud, counterfeiting, and theft. Interpol estimates that worldwide counterfeit goods represent 5 to 7 percent of all world trade or $600 million annually. In most cases, these security patterns come pre-printed on digital print media. The digital print media must be stored in a secure location so that counterfeiters and thieves are not able to obtain the security patterns. If a counterfeiter was able to obtain the media, they would be free to print fraudulent security documents that would be very hard to detect.

There are digital printers that can print these secure patterns on demand on standard media. The advantage of these printers is that the standard media does not have to be secured and guarded against theft. Security patterns can be created on demand. However, the printer must be set up with features/methods that disable the printing of these security patterns if a thief were able to steal the printer.

For example, some or all of the discussed patents/publications/products may not be sufficiently early in time, may not reflect subject matter developed early enough in time and/or may not be sufficiently enabling so as to amount to prior art for patent law purposes. To the extent that specific patents/publications/products are discussed above in this Description of the Related Art Section and/or throughout the application, the descriptions/disclosures of which are all hereby incorporated by reference into this document in their respective entirety(ies).

SUMMARY OF THE INVENTION

Various embodiments of the present invention may be advantageous in that they may solve or reduce one or more of the potential problems and/or disadvantages with conventional unsecured digital printers that can print these secure patterns on demand on standard media.

Various embodiments of the present invention may exhibit one or more of the following objects, features and/or advantages:

It is a principal object and advantage of the present invention to provide a digital printer that can print these secure patterns on demand on standard media and includes features/methods that disable the printing of these security patterns if a thief were able to steal the printer.

In accordance with the foregoing principal object and advantage, an embodiment of the present invention is directed to a digital printer including one or more of the following. First, an encrypted key is loaded into its memory that is uniquely tied to the printer serial number, where the printer will open areas of its memory where the security patterns are stored when this key is present. The security patterns or features can include, for example, pantographs, watermarks, microprinting, verification grids, validation marks, color, uv and/or IR marks, unique barcodes, serial numbers, anti-copying marks such as an Eurion mark, any combination thereof, and any other security patter as should be understood by those of skill in the art. The key can also enable upgrades to the printer by opening up an area of the printer's memory to load, as well as retrieve, security patterns. Second, the printer can have a unique password loaded into its memory. With this password in its configuration memory, the printer will be configured to look for a matching password to be present in the header of the data stream sent from the host software application (preferably running on a computer separate from the printer). If the password is not present in the data stream, the printer will not print the security patterns. A customer setting up the printer for the first time is encouraged to make this password a unique alphanumeric password. In accordance with an embodiment of the present invention, the password and the key loaded into the memory, and the password that will be present in the data stream, can be changed by a user/owner of the printer (e.g., an authorized user),

This unique printer configuration has been designed to prevent unauthorized use of the printer. If a printer is stolen, the key will be present on the device, but when the thief attempts to print a security pattern; the host computer will not have the matching password in its header. Thus, the security pattern will not print. If a printer is purchased without the key and a customer attempts to print the security patterns, it will not print. They will need to purchase a license which provides them the key to load into the printer memory.

The details of one or more embodiments are described below and in the accompanying drawings. Other objects and advantages of the present invention will in part be obvious, and in part appear hereinafter.
